Distributed mobility management with ID/locator split network-based for future 5G networks

The challenge to provide seamless mobility in the near future emerges as a key issue. By a brief analysis of the drawbacks of existing mobility management mechanisms, this paper presents the essential reasons why the traditional network model employing the IP protocol cannot provide mobility support for the end-host. This paper produces a distributed mobility management scheme with ID (identification)/locator split network-based, named IDN. It can provide more efficient mobility performance without Triangle Routing. By applying the IDN scheme to the legacy network, the hierarchy of the legacy network can be evolved into one layer ASN architecture instead of 2 layers. A mobility protocol performance analysis model is created, which is applied for a performance comparison between IDN scheme and the other existing mobility protocols. The simulation results show that the IDN scheme can save resources due to elimination of the Triangle Routing up to 18–64%. A qualitative comparison among those main existing network-based approaches is proposed, such as locator/ID separation protocol (LISP) and distributed mobility management (DMM) approaches. The four main weaknesses of host-based mobility management protocols can be overcame by the IDN scheme.
